Problems solved by technology

[0002] Chucks are commonly used fixtures on machine tools. Most of the existing chucks are driven by spiral grooves. The spiral grooves are set on the bevel gear. The chuck seat is equipped with radial chute, and the jaws of the chuck are installed in the radial chute. , and the bottom of the claw is equipped with a slider that matches the spiral groove. The expansion and contraction of the cylinder or hydraulic cylinder drives the rotation of the bevel gear, and the spiral groove on the bevel gear drives the claw to move along the radial chute. The distance of radial movement is much smaller than the telescopic distance of air cylinder or hydraulic cylinder, resulting in a small working stroke range of the chuck. Therefore, the diameter range of parts that can be clamped by this chuck is small, and the synchronization of each claw of the spiral groove drive is poor.

Abstract

The invention provides a chuck and a machine tool. The chuck comprises multiple claws, transmission gears and a driving device, wherein the bottom of each claw is provided with first teeth; the number of the transmission gears is equal to that of the claws, and the transmission gears are meshed with the first teeth respectively; second teeth are arranged on the driving device and meshed with all the transmission gears and can drive the claws to move through the transmission gears. The chuck provided in the scheme is large in work stroke range, the claws are high in synchronism, and the chuck is simple in part structure, low in production cost, easy to install and operate, convenient to repair and low in weight.

Description

technical field [0001] The invention relates to the field of mechanical processing, and more specifically, to a chuck and a machine tool with the chuck. Background technique [0002] Chucks are commonly used fixtures on machine tools. Most of the existing chucks are driven by spiral grooves. The spiral grooves are set on the bevel gear. The chuck seat is equipped with radial chute, and the jaws of the chuck are installed in the radial chute. , and the bottom of the claw is equipped with a slider that matches the spiral groove. The expansion and contraction of the cylinder or hydraulic cylinder drives the rotation of the bevel gear, and the spiral groove on the bevel gear drives the claw to move along the radial chute. The distance of radial movement is much smaller than the telescopic distance of air cylinder or hydraulic cylinder, resulting in a small working stroke range of the chuck. Therefore, the diameter range of parts that can be clamped by this chuck is small, and th...
